Abstract

PURPOSE:To efficiently execute embroidery and to obtain beautiful embroidery patterns without any color mixture by providing an arithmetic control means to operate a needle falling point and to control the movement of an embroidering frame so that an over-spreading thread, which is between the embroidery patterns of a same color, can not be sewn by the embroidery pattern, which is next sewn, in the other color. CONSTITUTION:In the formation of the embroidery pattern, concerning the problem of the over-spreading thread, which is formed by the jumping of a first control means, between the embroidery patterns of the same color, for example, when characters (a) and (r) are in the same color and characters (f), (t) and (e) are in the different color, the embroidering frame is moved by a movement control means so that the needle falling point can pass through positions to be shown by points (i), (j), (k), (l), (m) and (n) when the embroidery is executed from the character (a) to the character (r). For respective steps, a distance to the first needle falling point (k) is obtained. Samely, distances H and W from the (i) point to the (k) point are obtained. Then, the embroidering frame is moved only by the obtained distances H and W. At first, the embroidering frame is moved up to the (j) point only by the W in an X-axis direction and after that, moved up to the (k) point in a Y-axis direction. Then, one stitch is put at the (k) point. A moving distance to the next needle falling point (l) is obtained and the embroidering frame is moved only by the obtained distance. Then, one stitch is put at the point (l) after the movement. Finally, the embroidering frame is moved through the (m) point to the (n) point which is an embroidery starting point.

To provide an automatic embroidery sewing machine having a first control means and a second control means for moving an embroidery frame to the coordinates where a color change code of another color appears in order to embroider the next embroidery pattern of another color. Furthermore, during the first control means, a needle drop point is calculated so that the crossing thread between the embroidery patterns of the same color skipped and formed by the first control means is not sewn into the embroidery pattern of a different color to be sewn next. This invention provides an automatic embroidery sewing machine including arithmetic control means for controlling the movement of an embroidery frame.
According to the present invention, when forming a multi-colored embroidery pattern, it is possible to minimize the number of replacements of embroidery threads, so that embroidery can be performed efficiently. Since the embroidery pattern is not sewn into the embroidery pattern of a different color, a beautiful embroidery pattern without color clusters can be obtained.

う問題があった。Here, in forming the embroidery pattern of the present invention, consideration will be given to the problem of the crossing thread between the embroidery patterns of the same color that are skipped and formed by the first control means. In Figures 14 and 15, when the letters a and r are the same color and the letter rte is a different color, the letters a and r are sewn together first, but if no treatment is given, the embroidered letter a The embroidery thread is drawn as a crossover thread ('r) between the sewing end point i of the character r and the sewing start point n of the letter r as shown in Fig. 15. There is a problem in that the crossing thread (T) is sewn into the thread, and it takes time and effort to remove the crossing thread later.

以下この移動制御手段について、主として第２図、第８
図及び第９図を参照しなから説明する。The movement control means will be mainly explained in Figs. 2 and 8 below.
This will be explained with reference to FIG. 9 and FIG.

の刺繍範囲の右上の点である。(41) Find the moving distance to the first needle drop point (point in Figure 1f). This point is the completed pattern of embroidery (letter a)
This is the upper right point of the embroidery area.

一般的に刺繍範囲は主として第８図に示ず各要素から構
成されており、実際の刺繍範囲はこれを元に拡大、縮小
率を掛けて使用する。Generally, the embroidery area is mainly composed of various elements not shown in FIG. 8, and the actual embroidery area is used by multiplying the enlargement or reduction ratio based on this.

In the case of '-D', the first needle drop point C' is w'(w' = pattern width (w)) in the X-axis direction from the reference point A.
X magnification) 11' in the Y-axis direction (5' = pattern height (b
)

しかし、刺繍が終了するのはｅ点であるので結果として
ｅ−Ｃ’間を移動する距離Ｈ，Ｗを求めればよい。However, since the embroidery ends at point e, it is only necessary to find the distances H and W traveled between e and C'.

１−［Ｗはそれぞれ １１−１＝ｈ−ｅ ｙＷ＝　−ｅｘ となる。1-[W is each 11-1=h-e yW=-ex becomes.

ｅｘ、ｅｙは夫々ｅ点のＸ軸方向、Ｘ軸方向のＡ点から

うに制御してらよい。With the above-mentioned processing of the crossing thread, in the process of moving from the sewing end point i of the letter a to the sewing start point n of the letter r in Fig. 11,
When moving the embroidery frame, the upward course position passes in the order of point J, point , and intersection point 1m, in order to form needle-to-needle stitches at point and point 9, respectively. In Figure 1t, in the process of moving from the stitching end point i of the letter a to the stitching start point n of the letter r, the embroidery frame is moved and the course position is directly adjusted to the point j and the m point. The stitches may be controlled so as to pass through the needles in sequence and form stitches one stitch at a time at each of these points.

られるという効果が得られる。(Effects) As described above, according to the present invention, even when forming a multicolored embroidery pattern, the need for replacing embroidery threads can be minimized, so embroidery can be performed efficiently. Since the crossing thread is not sewn into the embroidery pattern of a different color to be sewn later, it is possible to obtain a beautiful embroidery pattern without color clusters.
